Cuff-pressure changes after the addition of 5 mL and 10 mL of air into the cuff of 3 artificial airways, after initial baseline of 30 cm H2O established. Cuff-pressure changes after the addition of 5 mL and 10 mL of air into the cuff of 3 artificial airways, after initial baseline of 30 cm H2O established. The cuff-inflation device was compared to the PressureEasy device and the syringe-inflation method. The first and second bar in each group represent the cuff pressure (from the calibration analyzer) measured after the additional injection of 5 mL and 10 mL of air, with the Sheridan endotracheal tube, the Microcuff endotracheal tube, and the tracheostomy tube.
